Improved method for manufacturing freeze dried dosages in a multilaminate blister pack.

Abstract

A multilayer laminated blister sheet (12) has an impermeable intermediate layer (14) positioned between first and second outer layers (16, 18), each of which has substantially the same coefficient of thermal expansion. The properties of the outer layers (16, 18) of the blister sheet are such that there are no interlayer stresses that will cause curvature of the blister sheet when it is subjected to temperature changes during freezing and freeze drying steps.
